2 ENVIRONMENT ECONOMY EQUITY 2

3 Eye Of The Storm INFRASTRUCTURE LAND USE VEHICLES ENERGY 1. Institutional structure 2. Lack of over-arching integration 3. Differential speed of public and private decisions 4. Ambiguity of transit, parking 5. Pattern breaks, niche markets, metamorphoses BREAD CHEESE WINE 3

4 1. Gateway Assignment A. Numbers matter, at least they should: Massachusetts Avenue carries as many people in peak buses as in autos Speed is important for longer trips, but 20 mph isn't so different than 50 mph as a top speed; when you look at travel time, avoiding 5 mph is the big issue. Pedestrians are often very important, but ignored. Bicycles are tiny, get a lot of attention, and complicate traffic a lot, but need safer conditions 4

5 1. Gateway Assignment (cont.) B. Actors matter: Problems are in the eye of the beholder Producers and Managers of Transportation -- surrogate customers "users" (customers): passengers, shippers Abutters affected by positive and negative externalities of transportation Government agencies and institutions whose missions may include protecting the interests of all of the above Information technology might increase the effective power of bus riders Who you are working for matters 5

6 2. Millennium Database A. What are the characteristics that matter in metropolitan areas, and how might they be changed over time? 6

7 3. Urban Design, Physical Characteristics Matter A. Sullivan Square B. Sullivan Station C. Rutherford Avenue D. City Square 7

8 Current National (and International) Context and Problems 1. Focus on debt and government deficit 2. Unemployment and stagnant economic growth 3. Markedly worse income distribution 4. Worsening climate change and other environmental threats Urban Transportation Planning 8

9 Current National (and International) Context and Problems (cont.) 5. Infrastructure maintenance, reconstruction and operations create substantial new financial needs interstate facilities over 50 years old growing congestion in most metro areas, simultaneously constraining goods movement aging population pose new mobility challenge no culture of operation and maintenance in most public work agencies Stagnant federal funding means costs are pushed down to states and local government Urban Transportation Planning 9

11 Government vs, Private GOVERNMENT PRIVATE Honest & competent Honest & incompetent Dishonest Honest & competent Honest & incompetent Dishonest 11

12 4. Pattern Breaks A. The future is not always a projection of the past B. Kierkegaard: History can only be understood looking backward, but it must be lived going forward C. What does President-elect Trump mean for the future? 12

13 Can We Be Realistic AND Positive? Currently 750 million vehicles in world. By 2050, number is projected to be 2 billion. [Factor of 3] Is it feasible to reduce petroleum consumption per vehicle by a factor of 4? Could we really change? Maybe. If we can implement a 20% fuel consumption reduction in each of 6 different areas: 0.86 = 0.26 Will require changes in technology, vehicles, system operation, and behavior. Technology is key, but not enough. From Prof. J Heywood s address at MIT Energy Forum, May

14 Getting to the Source of Pollution Pollution = Pollution = f(land use, transit, income, auto industry, density, roads) Externalities are external and Culture eats policy for breakfast Terry Stone Urban Transportation Planning - Fall

15 Ways to Impact Energy Use: Behavior 1. Encourage less aggressive driver behavior 2. Increase vehicle occupancy on substantial fraction of trips 3. Reduce mileage driven per person per year 4. Substitute bio-mass fuels for petroleum fuels 5. Manage existing transportation system more effectively (ITS) 6. Increase public transit utilization Adapted from Prof. J Heywood s address at MIT Energy Forum, May

16 Ways to Impact Energy Use: Technology 1. Shift the vehicle performance/fuel economy tradeoff towards lower fuel consumption 2. Improve vehicle maintenance, lubricants, tire pressure, reduce parasitic loads 3. Lighter weight, less big vehicles 4. Implement more efficient engine, drivetrain, and vehicle technologies 5. Develop and implement use of hydrogen as an energy carrier with fuel cell powered vehicles 6. Use electricity with advanced battery technologies to shift part of transportation energy demand away from petroleum Adapted from Prof. J Heywood s address at MIT Energy Forum, May

17 Way to impact energy use: Regional Connectivity A. Locate jobs where there is good transit B. Significantly increase good transit, and transit accessible locations C. Encourage employees to use transit D. Upgrade significantly the quality of urban spaces (people will eat more spinach if it tastes good) From Prof. J Heywood s address at MIT Energy Forum, May

18 Objective Reality Capital investment in the interstate has now been implemented Operation and maintenance is inadequate throughout the country Capital needs most significant in growing economies Time for a national pattern break? O&M, at everywhere? Return to sender? Local and state flexibility? Metro areas more important than states but states are written into the constitution Urban Transportation Planning - Fall

19 Objective Reality (cont.) Agency culture Public private partnership Capital investment by rational criteria Institutional reality Construction industry Vehicle procurement Urban Transportation Planning - Fall

20 Charity Begins at Home 1. California referenda 2. Massachusetts 1964 MBTA statue 3. London cross rail lesson 4. Toronto exercise in business 5. Political will Urban Transportation Planning - Fall

21 Conditionality Davis Bacon Environmental law Environmental justice Integrity; Trump legacy Urban Transportation Planning - Fall

22 Boston is Manhattan surrounded by Phoenix Boston is blue state surrounded by rust belt Why should North Adams pay for Boston bus ride? Urban Transportation Planning - Fall

23 Return to Sender, with transparent rules will build political wills, and distribute more money to rusty area Better for Boston than discretion and grants And, More likely to be supported politically Urban Transportation Planning - Fall

24 Which should be the next priority? 1. Really complete the Green Line extension? 2. The Blue to Red connector? 3. The missing link of the Silver Line? 4. The Stuart Street subway 5. South Coast Rail 6. Grade separate Silver Line at D Street 7. The north to south rail track? Synecdoche Waiting for lefty Urban Transportation Planning - Fall

25 Self Reliance But national tax collection is most effective so embrace return to sender Plus vehicle and signal manufacturing promotion at National level Large capacity increase (tunnels, subways) would benefit from national support Contracting out is fine with Davis Bacon Urban Transportation Planning - Fall

26 How to pay for this? Local and State Gas tax Carbon tax Sales tax Property tax VMT tax Interstate Compact Gasoline tax Carbon tax National Carbon tax Petroleum company Excise tax Urban Transportation Planning - Fall
